/**

 * 升级短信通知， 如果有ThinkPHP新版升级，或者重要的更新，会发送短信通知你。

 * 需要使用SAE的短信服务。请先找一个SAE的应用开通短信服务。

 * 使用步骤如下：

 * 1，在项目的Conf目录下建立tags.php配置文件，内容如下：

 * <code>

 * <?php

 * return array(

 *   'app_init' =>  array('UpgradeNotice')

 * );

 * </code>

 *

 * 2，将此文件放在应用的Lib/Behavior文件夹下。

 *注：在SAE上面使用时，以上两步可以省略 

 * 3，在config.php中配置：

 *  'UPGRADE_NOTICE_ON'=>true,//开启短信升级提醒功能 

 * 'UPGRADE_NOTICE_AKEY'=>'your akey',//SAE应用的AKEY，如果在SAE上使用可以不填

 * 'UPGRADE_NOTICE_SKEY'=>'your skey',//SAE应用的SKEY，如果在SAE上使用可以不填

 *'UPGRADE_NOTICE_MOBILE'=>'136456789',//接受短信的手机号

 *'UPGRADE_NOTICE_CHECK_INTERVAL' => 604800,//检测频率,单位秒,默认是一周

 *'UPGRADE_CURRENT_VERSION'=>'0',//升级后的版本号，会在短信中告诉你填写什么

 *UPGRADE_NOTICE_DEBUG=>true, //调试默认，如果为true，UPGRADE_NOTICE_CHECK_INTERVAL配置不起作用，每次都会进行版本检查，此时用于调试，调试完毕后请设置次配置为false

 *
